HARRY B. HILLS, OE ToMrKINsvILLE, NEW YORK, ASSIGNOR To STEWARZD DAVIT &EQUIPMENT CORPORATION, on NEW YORK, N. Y., A CORPORATION on NEW YORK.

SHIPS DAVIT.

Application filed June 25, 1919.

To all whom 2'25 may concern:

Be it known that I, HARRY B. HILLS, a citizen of the United States,residing at iompkinsville, county of Richmond, and State of New York,have invented certain new and useful Improvements in Ships Davits, ofwhich the following is a specification.

My invention relates to a ships davit, and it has for its object theprovision of means whereby it can be lowered or moved from its operatingposition onto the deck of the boat and without being dismantled or takendown, so as to leave the space occupied by it free for other purposes. 1

I will describe a ships davit embodying my invention and then point outthe novel features thereof in claims.

In the accompanying drawings, Figure 1 is a top view of a framecomprised in a ships davit, partly in cross-section and embodying myinvention. Fig. 2 is a side elevation of the davit shown in Fig. 1. Fig.3 is a view showing in dotted lines how the davit frame moves on itshinge. Fig. 4C is a view similar to Fig. 1, but showing a modificationembodying my invention.

Similar letters of reference designate corresponding parts in all of thefigures.

I will premise that my invention is ap plicable to that type of shipsdavit which embodies a frame or other support on which is suitablymounted a boom, by means of which a lifeboat is launched or decked. Inthe drawings I have illustrated only the frame or support of a shipsdavit, because my invention is associated with it. The form of frameillustrated is substantially that shown inU. S. Patent No. 1,245,752,granted November 6, 1917 to T. H. Marten, and my invention isparticularly applicable to that form of ships davit.

Referring to the drawings, A designates a suitable frame comprising abase a and uprights a (1. The frame may be constructed in any desiredway in order to obtain the necessary strength and rigidness for the workto be performed. Preferably the frame is cast of metal and in a unitarystructure. The frame is suitably mounted on the deck of a ship insuitable position so that the boom mounted thereon may be moved outboardand inboard in launching and decking a lifeboat. As here shown the frameis mounted on sole pieces B, and the sole Specification of LettersPatent.

pieces are suitably fastened to the deck by means of bolts Z) or otherfastening devices.

Suitably secured to the base a, where the uprights a a are joined to it,as by rivets c, are plates C C C C arranged in pairs. The plates C C anlarger than the plates C C and a greater number of rivets c are used,because these plates are on the inboard side of the davit and aresubjected to greater strain. So far as my invention is concernedhowever, they perform the same function as the plates C C Each plate hasa hinge connection D with the adjacent sole piece B, and with one ormore recesses 0 each of which receives a tumble bolt E, which are hingedon the sole pieces B. The frame A is held in its upright or operatingposition on the sole pieces B by means of the tumble bolts E.

It will be observed that when it is desired to lower the davit onto thedeck it is only necessary to remove all of the tumble bolts E from therecesses c and turn the frame on a pair of its hinges D (see Fig. Onepair of hinges D is used to lower the davit in one direction while theother pair is used to lower the davit in the opposite or reversedirection. I have only shown in the draw ing's two pintles (Z, and theseas being removable, so that they may be used in either pair of hinges.

In Fig. a T have omitted the sole pieces B. In this form of my inventionthe tumble bolts E are suitably secured to the boat deck as are theparts (Z of the hinges D.

My invention is particularly useful when lifeboats are located near ahatchway which is used for loading and unloading goods. The davits atthese points be lowered out of the way of the freight boom without beingdismantled and quickly put back into position after the loading orunloading is completed.

Having thus described my invention, what I desire to claim as new is 1.The combination of a ships davit frame, a pair of plates securedthereto, a hinged connection between each. of said plates and the deckof the boat, and removable means secured to the deck of the boatengaging said plates for holding the frame against movement on itshinged connections.

2. The combination of a ships davit frame, a pair of sole pieces securedto the deck of a boat, a pair of plates secured to the fi'aine, a hingeconnection between each name to this specification, in the presence ofplate and ad acent sole piece, and relnovtwo subscribed Witnesses.
